Do you start a new pack when your period starts or after its done?

That's a question that should have been answered by your doctor when you receivd your prescription. Perhaps it would be better to ask your pharmacist or physician rather than require people here to answer SPECIFIC medical questions. Hello. You need to start a new pack of pills after the seven day break from pills. If you start a new pack right away you wont have a period and this could mess up your future cycles.
